I have an 80's vintage John Deere 1032 (10hp, 32" sweep). It gets 25-35+ hours of tough use/abuse each winter and I'm surprised it's lasted this long.
It's a somewhat tough machine but most of the controls have broken or fallen off over the years ... as well as the shielding around the engine. I've cobbed together replacement components and fasteners ... in many cases making the machine beefier than original.
The whole thing shakes and vibrates unreal and that has a lot to do with the small part failures, I'm sure. I've replaced the drive belts a few times, the drive wheel twice and last winter the side bushings wore out, caused the axle to misalign, broke a chain and sheared the main drive axle itself. Cost over $100 for parts alone ... but that's a lot cheaper than a new one.
At the end of last season, I noticed that the plate the motor sits on is cracked ...
severely cracked ... in a couple places. Vibration again, I'm sure. The blower left in April to be fixed/welded. Have to find out where it is. Gonna need it back by Thanksgiving.
It doesn't appear the newer John Deeres are made this rugged, however.
If you are doing a lot of blowin', I'd be tempted to buy that monster Toro with the dual wheels. I think it uses a 13-15hp motor and has a 42" or wider cut. I saw one in a local Home Despot. I just grabbed the handles in the store and felt a primal growl run through me.
